Contingencies

The Company is subject to claims and assessments from time to time in the ordinary course of business. The Company records a provision for a liability when it believes that it is both probable that a liability has been incurred and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount.

In the normal course of business, the Company may become involved in legal proceedings. The Company will accrue a liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. When only a range of possible loss can be established, the most probable amount in the range is accrued. If no amount within this range is a better estimate than any other amount within the range, the minimum amount in the range is accrued. The accrual for a litigation loss contingency might include, for example, estimates of potential damages, outside legal fees and other directly related costs expected to be incurred. The Company was subject to an arbitration claim that arose in the ordinary course of business at September 30, 2017. This claim was settled in the fourth quarter of fiscal year 2017. At December 31, 2017, the Company was not involved in any material legal proceedings.

Purchase Commitments

At December 31, 2017 and 2016, the Company had no outstanding firm purchase commitments.
